rail 

To fuck a chick really hard and roughly. Usually involves kinky and dirty positions and the guy's intent is to often cum in her face, finish the job, get maximum pleasure in a minimum amount of time...so he can move on to rail the next girl.

Wow, Lauren is hot. I'm gonna rail her tonight and she won't even know what hit her.
